New Fiber-Matrix Composites with Negative Poisson's Ratio
INV-23063 Background Materials with a negative Poisson's ratio, known as auxetics, have been studied for use in applications that can resist in-plane or out-of-plane loads. When stretched these materials uniquely expand perpendicular to the applied force. However, their widespread adoption faces significant hurdles due to their typical foam-like,...

An OCT method to improve scleral lens fitting
Summary The current technology allows for accurate and objective 3-dimensional (3D) mapping of the external limbus, which could ultimately improve the process of scleral lens fitting. Technology Overview Rigid scleral lenses are difficult to fit to patients because they must rest on the eye but vault over the cornea and the limbus, which is the transition...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...
